Definitions

  • the invention relates to a stirrup prosthesis for implantation in the middle ear with an elastic clip which can be pushed onto the long anvil extension in the form of a clamp open on one side.
  • the present invention is therefore based on the object of improving the known stirrup prosthesis in such a way that its implantation is even easier.
  • the handling of the prosthesis can also be facilitated by the fact that it can be provided on its outside with a nipple for pushing the prosthesis on the long incus process. At this nipple the surgeon can attack with tweezers or a hook.
  • the clip may also be provided on its opposite side of the opening with a notch for pushing the prosthesis on the long incus process. Also at this notch a corresponding instrument can be attached.
  • the clip which does not completely encompass the long incus process.
  • the formation of constrictions on the long process of the incus and thus the occurrence of potential necroses can be prevented.
  • the clip is arranged on the long process of the incus, so that it does not bear on it in two regions of the circumference of the long process of the incus.
  • the supply vessels on the long incus process are affected only in the investment areas. The remaining vessels run in the two areas where the clamp does not rest against the incus process, so that the nutrient supply to the long anvil process and the Proc. Lenticularis is not endangered.
  • the prosthesis can be made of any biocompatible material. Particular advantages arise when at least the clip is made of titanium, since this material has excellent biocompatibility in the human middle ear.
  • Stirrup prosthesis 10 shown is formed by a piston-shaped part 11, which sits with its lower end face 11.1 in the oval window and thus transmits the sound to the inner ear.
  • a prosthesis shaft 12 connects, which has at its upper end a clip 13 made of an elastic material.
  • the clip 13 is formed in the form of a one-sided open bracket. It can be pushed with its opening 14 over the long incus process.
  • the upper leg 13.1 of the bracket 13 is extended beyond the opening 14 and forms there an arc 15 with which the entire prosthesis 10 can be hung on the long incus process.
  • a nipple 16 is arranged, on which the surgeon can attack, for example with tweezers or a hook.
  • the clip 13 of the prosthesis 10 is designed such that it surrounds the anvil extension three-quarter circle, the prosthesis 20 points out Fig. 2 a clip 23 which contacts the long anvil extension only in two areas 23.1 and 23.2.
  • the intermediate region 23.3 runs in one relatively large distance from the incus process, so that there the supply vessels of the long process of the incus can not be pinched off by the clip 23. Otherwise, the clip 23 is similar to the clip 13 is formed.
  • the upper leg again has an arcuate portion 25 with which the prosthesis 20 can be hung on the long incus process.
  • a nipple for attaching a surgical kit is provided on the outside of the clip 23 again.
  • the prosthesis 30 off Fig. 3 has a clip 33 which is very similar to the clip 23 Fig. 2 is shaped.
  • a notch 37 is now provided in the region 33.3 of the clip 33 opposite the opening 34, in which an operating set can likewise be applied in order to push the prosthesis 30 onto the long incus extension.
  • the prostheses 10 to 30 also differ in their length and also in the thickness of the piston-shaped parts 11, 21 and 31.

  1. Prothèse d'étrier (10 ; 20 ; 30) pour implantation dans l'oreille moyenne, comprenant une tige de prothèse (12 ; 22 ; 32) et un clip élastique qui y est fixé et peut coulisser sur le long prolongement de l'enclume sous la forme d'une agrafe (13 ; 23 ; 33) ouverte d'un côté, qui présente deux branches (13.1, 23.1, 23.2 ; 33.1, 33.2) en regard l'une de l'autre et courbées à l'état implanté de la prothèse (10 ; 20 ; 30) autour du long prolongement de l'enclume, lesquelles branches laissent libre entre elles une ouverture (14 ; 24 ; 34), dans laquelle l'agrafe (13 ; 23 ; 33) est prolongée, sur au moins une première branche (13.1 ; 23.1 ; 33.1), par un arc (14 ; 24 ; 34) prolongeant la première branche (13.1 ; 23.1 ; 33.1) et s'étendant vers l'extérieur dans la direction de la branche au-dessus de l'ouverture (14 ; 24 ; 34),
    caractérisée en ce que
    l'agrafe (13 ; 23 ; 33) est raccordée, sur sa seconde branche (23.2 ; 33.2) opposée à sa première branche (13.1 ; 23.1 ; 33.1), à la tige de prothèse (12 ; 22 ; 32) de sorte que la tige de prothèse (12 ; 22 ; 32) se situe dans le plan de l'agrafe et s'étende de la seconde branche (23.2 ; 33.2) radialement vers l'extérieur en s'écartant de l'agrafe (13 ; 23 ; 33),
    et en ce que l'arc (15 ; 25 ; 35) est courbé dans la même direction que celle de la première branche (13.1 ; 23.1 ; 33.1) de sorte que la prothèse (10 ; 20 ; 30) puisse être suspendue avec l'arc (15 ; 25 ; 35) sur le long prolongement de l'enclume de l'oreille moyenne humaine avant son coulissement.
  2. Prothèse selon la revendication 1, caractérisée en ce que l'agrafe (13, 23, 33) est pourvue, sur son côté externe, d'unnipple (16, 26, 36) pour faire coulisser la prothèse sur le long prolongement de l'enclume.
  3. Prothèse selon la revendication 1 ou 2, caractérisée en ce que l'agrafe (13, 23, 33) est dotée, sur son côté (33.3) opposé à l'ouverture (14, 24, 34), d'une encoche (37) pour faire coulisser la prothèse sur le long prolongement de l'enclume.
  4. Prothèse selon l'une quelconque des revendications 1 à 3, caractérisée en ce qu'après l'implantation, le clip (23, 33) est agencé sur le long prolongement de l'enclume de sorte qu'il s'appuie seulement sur celui-ci dans deux zones (23.1, 23.2, 33.1, 33.2) du pourtour du long prolongement de l'enclume.
  5. Prothèse selon l'une quelconque des revendications 1 à 4, caractérisée en ce qu'au moins le clip (13, 23, 33) est fabriqué en titane.
